Text file claims E2M2 but it's Doom2 level 10. Gormless readme; the map has lots of big fights (mostly shotgun guys and imps) but it's not a challenge at all. I played it whilst listening to "Frightened in France" by Kissing the Pink, from their 1983 album Naked. It has a nice robot voice effect and some classic electro percussion. Rubbish lyrics, though.
